My speedster is going to be the traditional speedster. Thinking she was working on making some Velocity 9 to sell to help her parents out with the finances and lightning strike (just for the good old fashioned part). Boom (literally & figuratively) she is now a speedster.

Maybe with Velocity 9 instead of blood, like if you were to cut her open and save what came out you could give yourself speed powers temporarily.

That last part sounds silly. May not use it unless someone really wants me to.
